Kostakan

Type
Pyroclastic cone
Elevation
1150m
Last eruption
1350
A N-S-trending chain of scoria cones lies in the Kostakan valley south of Bakening volcano. The 600-year-old Glavny scoria cone (left center) is surrounded by its lava flow, which dammed a small river to form beautiful Kostakan lake. Two small vegetated early Holocene cones lie along the opposite side of the lake.
